Hello

while trying to deploy my charm under "local" env, when it tries to downlload pip package for charmhelpers purpose I get messages like: 

unit-kimchi-0[871]: 2015-03-03 15:09:55 INFO unit.kimchi/0.install logger.go:40 E: Failed to fetch http://ports.ubuntu.com/ubuntu-ports/pool/universe/p/python-pip/python-pip_1.5.4-1_all.deb  Cannot initiate the connection to ports.ubuntu.com:80 (2001:67c:1360:8001::18). - connect (101: Network is unreachable) [IP: 2001:67c:1360:8001::18 80]

like if it is willing to use IPv6 when network is configured as : 

ubuntu@u0016001-local-machine-3:~$ ifconfig -a

My lxc config file is: k$ cat /etc/lxc/default.conf 
 lxc.network.type = veth

 lxc.network.link = lxcbr0
 lxc.network.flags = up
